gives an overall
picture of audio pro-
cessing action. The Web
interface gives a 2-color
display that additionally
provides audio level and
gain reduction annota-
tion. The two examples
here reflect the same
program, but not quite
at the same moment.
Processing Presets
The NOVIA 272 comes with ten factory-programmed pro-
cessing presets and ten empty registers where you can save
your own, customized ones. We recommend that you start
with one of ‘ours’ and nurse it into ‘yours,’ something that
sounds best for your programming and market de-
mographics.
In this contrived exam-
ple, ‘Bob,’ the station’s
P.D., has developed his
own version of our fac-
tory
(F) Country
preset,
and has renamed it
Country-2 (Bob’s)
. All processing parame-
ters are saved in each preset, and presets are saved along
with all other user settings when you download a Hardware
Profile backup (see Page 30).
Creating presets is easy. After you have nursed-in just the
right sound for your station, scroll to the top of the
Presets
menu to
Save Preset
. Push the knob and, as instructed,

preset at the bottom of the list.
To delete a custom preset, scroll to the bottom of the list
and select

Setting Input Levels
Adjust the appropriate
Input Level
under
Setup/Inputs

…
(whichever input:
Analog
,
Digital
or
Stream
applies).
Setting the level of the program source involves matching
the dynamics of the incoming program audio to those of the
‘gain-riding,’ slow-AGC function. It’s best to use program
audio for this rather than tones. With moderately pro-
cessed off-air feeds and contemporary music releases, pro-
gram peaks should consistently reach
–3dB
on the front-
panel LED meters. Heavily processed music may need to be
backed-down so peaks don’t go above
–6dB
. Material with a
wide dynamic range may occasionally reach
0dB
. For a de-
finitive measurement, go to
Setup/Processor/Meters
and check
AGC
meter action. The aim is to keep this meter hovering
right around
0dB
(center-scale) most of the time.
AGC
AGC is a slow, wideband ‘gain-riding’ function that presents
subsequent processing stages with a uniform level based on
both the peak and the average content of the audio pro-
gram. AGC is ‘gated’ to prevent ‘gain runaway’ during silent
periods.
The front-panel
AGC
indicator lights when the gate is open.
The
AGC
designation below the OLED and Web interface
meters is at normal brightness under this condition. The
LED goes off and
AGC
grays-out during pauses in the
program.
AGC is ‘windowed’ as well. This means that when AGC gain
drifts outside its ±5dB ‘sweet spot,’ accelerated ‘makeup
gain’ brings it back inside more quickly.
AGC is enabled
AGC
by default, but may be turned off for
classical or jazz music to preserve
pianissimo
passages.
